My touchpad is not working at all on ubuntu

[STEFANOS Marie-Ange]

I have followed this tutorial https://wiki.ubuntu.com/DebuggingTouchpadDetection#In_case_your_Touchpad_doesn.27t_work_at_all_.28No_response_from_the_Touchpad.29
But no touchpad device appears when I execute at terminal cat /proc/bus/input/devices

My laptop is a Lenovo ThinkBook 15-IIL (20SM000GFR)

Thank you for your help

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Hi, thanks for your answer.

Now I know that is a security issue and not a bug.
How can I fix this to be able to use the touchpad on Ubuntu on my laptop ?
